Title: Gearing for driving superchargers for internal combustion engines
IPC: F16H63/30
Filed: 1934-03-16
Abstract: 432,448. Change-speed gearing; driving fans. RUBBRA, A. A., Red Roofs, Carlton Road, Derby. March 16, 1934, No. 8313. [Class 80 (ii)] [See also Group XXVI] In a two-speed epicyclic gear for driving the supercharger fan b<6>, Fig. 1, of an internalcombustion engine, the change from low to high speed is effected by applying a plate brake g to an annulus d<3>. This change may be effected by moving a handle k<1>, Fig. 2, so as to admit pumped oil between pistons j, j<1> to turn a control ring h right of Figs. 2 and 4 and so to break toggles h<2> which hold the brake g out, so that springs g<5> are freed to engage the brake. The annulus d<3> is thus held fast, and the smaller steps d of double planets d, d<1> track round upon this annulus and drive a sun gear e on the fan shaft b<5> at high speed. The double planets, d, d<1> are supported on a carrier b<3> fast on the engine shaft b. A larger annulus d<4> meshing with the larger planet steps d<1> is now turning idly backwards. To return to low speed, the handle k<1> is moved back so as to admit oil outside the pistons j, j and press them inwards together. The ring h, a thrust ring supported behind by ball bearings h<1>, is now turned left as shown by arrows in Figs. 2 and 4. The toggle links h<2> are thus brought to a propped position holding the springs g<5> compressed with the brake g disengaged. The larger annulus d<4> now takes the reaction on the low speed. It is prevented from turning idly forwards by a oneway brake f<2>, Fig. 1. A slip clutch between the sun gear e and the shaft b<5> prevents shocks being transmitted to the fan b<6>.

Title: Improvements in and relating to the regulation of gas turbines
Filed: 1938-03-18
Abstract: 498,639. Gas turbines. AKT.-GES. BROWN, BOVERI, & CIE. March 18, 1938, No. 8362. Convention date, March 18, 1937. [Class 110 (iii)] A gas turbine 1 drives an electric generator 5 which provides electricity for the motor 6 of a vehicle. The output is regulated by a fuel valve 7 and the air supply from the compressor 3 is correspondingly adjusted by varying the speed of the turbine, compressor, generator set independently of the output. This is done by varying the field excitation of the generator. In the form shown, the field excitation is varied by means of a rheostat 16, which, through a servomotor 14, 15, is controlled by devices 10, 11 responsive to the flow, respectively, to the fuel at the point 12 and the air at the point 13. The rheostat may be under the control of a thermostat in the outlet of the combustion chamber, or, a thermostat in the exhaust of the turbine in conjunction with a device responsive to the initial gas pressure or the speed of revolution. Further, the rheostat may be controlled by a speed-governor in conjunction with a device responsive to the flow of fuel. To expedite the adjustment, the excitation may be given an initial variation before varying the fuel supply.

Abstract: 736,543. Reciprocating motors. STANDARD TELEPHONES & CABLES, Ltd. March 27, 1953 [May 15, 1952], No. 8529/53. Class 35. [Also in Group XXXVIII] A polarized electromagnet used for example to operate a bell comprises a permanent magnet 3 connecting two ends 14 of a pair of similar iron stampings 1, 2, a T-shaped armature 8 pivoted near the other extreme ends of these stampings, and a coil carrier surrounding the vertical leg of the armature 8. The free end of the armature vertical leg terminates adjacent two end parts 4, 5 of the stampings 1, 2. When the coil 9 is fed with A.C. the armature 8, together with its axle 12 oscillates about the axis of the latter, these oscillations being dependent upon the resulting interaction of the fluxes of the permanent magnet and of the A.C. and upon the closing of the magnetic paths due to the co-operation of the four free ends of the armature 8 and the four pole-pieces 4, 5, 6, 7 of the stampings 1, 2. Fig. 7 shows the complete assembly of the device for use as an electric bell wherein the armature horizontal part is provided with anti-sticking members 25 at its extreme ends.

Abstract: 1,007,306. Steam turbine plant. ENGLISH ELECTRIC CO. Ltd. March 6, 1962 [March 14, 1961], No. 9228/61. Heading F1T. In a reheat steam turbine plant including a multi-stage turbine 11, 12, 13, bled steam reheater means in a reheater 18 are arranged for reheating turbine steam extracted from a first point between the points of highest and lowest pressure in the turbine by steam bled from a second point 11 A at a higher pressure than the first point. Live steam which may be supplied by a nuclear steam generating plant, is supplied through a pipe 14 and at a lower pressure to a pipe 16 leading to the intermediate pressure stage of the turbine. The bled steam passes from a coil 21 of the reheater 18 to a feedwater heater 25 via a drain tank and flash box 42 and the turbine steam is returned to the low pressure stages. Further steam may be extracted upstream of the first point and passed through a reheater coil 23, passing on to a flashbox 28, which drains to the feedwater heater 25. The steam flashed off from the flashbox 28 is supplied to the coil 21 and the water content of the steam in the flash box 42 passes to the turbine condenser via a pipe 27.
